の主軸台。 In the headstock of a machine tool in which a quill supporting the spindle is inserted into the headstock body, an air inlet is provided between the middle part and the rear of the headstock body, and an air passage is formed from the air inlet toward the front side. The air passage communicates with the space between the quill and the headstock body on the front end side of the headstock body, opens the rear side of the space between the headstock body and the quill, and uses the opening as a suction port for the blade. A machine tool headstock that has a wheel fixed to the main shaft and is equipped with a cooling means that allows the discharge side of the impeller to communicate with the atmosphere.
